GMTCAuthorization
@protocol GMTCAuthorization <NSObject>
Protocol used to provide authorization tokens for gRPC calls. These tokens
give access to the Fleet Engine service accounts.
The implementation should ensure that a valid authorization token is always available.
The authorization token should have a minimum lifetime of 5 minutes to allow for requests to
complete. Therefore, the authorization token must automatically renew expiring tokens and
minimize the number of token refreshes by re-using a token until its lifetime nears its end.
Implementations of this protocol must be thread-safe.
-
Called by the SDK to fetch a JWT. The implementation must assume that this method
may be invoked from arbitrary queues.
Parameters
authorizationContext
|
The context of the target authorization token.
|
completion
|
Must be called asynchronously, but can be called from any queue.
